Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0037] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0038] like Figures 1 to 8 As shown, a permeable brick pavement structure comprises a compacted base soil layer 1, a crushed stone layer 2 is laid on the top surface of the compacted base soil layer 1, a concrete layer 3 is laid on the top surface of the crushed stone layer 2, and a permeable brick pavement layer is laid on the top surface of the concrete layer 3;

[0039] The permeable brick pavement layer is obtained by paving multiple permeable brick bodies 5. A positioning boss 502 is provided at the lower end of the permeable brick body 5. The positioning bosses 502 of adjacent permeable brick bodies 5 are in contact, and a permeable seam is formed between the upper ends of adjacent permeable brick bodies 5. A permeable groove 506 is provided at the edge of the lower end of the permeable brick body 5. A connecting groove 503 is provided on the positioning boss 502. One end of the connecting groove 503 is connected to the permeable seam, and the other end is connected to the permeable groove 506; a permeable channel is formed between the permeable grooves 506 of adjacent permeable brick bodies 5, and a connecting channel is formed between the connecting grooves 503 of adjacent permeable brick bodies 5.

[0040] Drainage channels 4 are provided on both sides of the permeable brick paving layer, and drainage holes 401 corresponding to the permeable grooves 506 are opened on the drainage channels 4.

[0041] The permeable bricks are square blocks with a diversion groove 501 at the top of the brick body 5. The diversion groove 501 connects to the permeable slits and forms a cross-shaped structure, allowing rainwater to flow quickly into the slits. A positioning boss 502 on one side of the permeable brick body 5 is provided with an insert plate 504. A slot 505 that mates with the insert plate 504 is provided on the positioning boss 502 on the side of the permeable brick body 5 away from the insert plate 504. There are two insert plates 504 and two slots 505.

[0042] The arrangement of the slots 505 allows two adjacent permeable brick bodies 5 to form a whole, thereby improving the flatness of the permeable brick paving layer. In some embodiments, the two inserting plates 504 of the permeable brick body 5 are arranged in two slots 505 of a permeable brick body 5 adjacent to each other (e.g. Figure 1 As shown), in other embodiments, the two plug-in plates 504 of the permeable brick body 5 are respectively in the slots 505 of the two adjacent permeable brick bodies 5 (as shown Figure 9As shown), at this time the permeable brick paving layer forms a whole, and the flatness is further guaranteed.

[0043] A horizontal pipe 6 is provided within the gravel layer 2, with a vertical pipe 601 provided on its sidewall. The vertical pipe 601 penetrates the gravel layer 2 and the concrete layer 3, corresponding to the position of the permeable groove 506. The horizontal pipe 6 communicates with the drainage channel 4. A through hole is provided on the sidewall of the horizontal pipe 6. The upper end of the vertical pipe 601 protrudes above the upper end surface of the cement layer.

[0044] When the rainfall is small, rainwater flows into the drainage channel 4 through the diversion groove 501, the permeable seam, the connecting channel, the permeable channel, and the drainage hole 401 in sequence.

[0045] When the rainfall is heavy, the rainwater enters the drainage channel 4 through the guide groove 501, the permeable seam, the connecting channel, the permeable channel, and the drainage hole 401 in sequence. The water level in the permeable channel rises above the upper end of the vertical pipe 601, and the rainwater flows into the drainage channel 4 through the vertical pipe 601 and the horizontal pipe 6 in sequence. There are through holes on the side walls of the horizontal pipe 6. If the amount of rain is too large, the water level in the drainage channel 4 is higher than the horizontal pipe 6, and the rainwater will enter the gravel layer 2 for temporary storage. When the water level in the drainage channel 4 is lower, it will flow into the drainage channel 4 through the through-hole horizontal pipe 6.

[0046] In other embodiments, a permeable geotextile is provided between the permeable brick paving layer and the concrete layer 3, and a medium sand layer is provided between the permeable geotextile and the permeable brick paving layer. The medium sand layer is obtained by paving and leveling fine sand, which facilitates the paving and leveling of the permeable brick body 5 above, thereby improving the paving efficiency. The permeable geotextile prevents the loss of fine sand and allows water to pass through.

[0047] Construction process:

[0048] S1, excavating the foundation and compacting it to form a compacted foundation soil layer 1;

[0049] S2. Laying the horizontal pipe 6 on the compacted base soil layer 1;

[0050] S3, laying a crushed stone layer 2 on the compacted base soil layer 1;

[0051] S4, laying a concrete layer 3 on the gravel layer 2 and leveling it;

[0052] S5, laying a plurality of permeable brick bodies 5 on the concrete layer 3 to form a permeable brick paving layer;

[0053] S6. Dig drainage ditches on both sides of the permeable brick pavement layer, and pour drainage channels 4 in the drainage ditches. The bottom of the drainage channels 4 is lower than the horizontal pipe 6.

[0054] Under different rainfall amounts, rainwater can flow into the drainage channel 4 through three pathways. The first pathway is through the gaps in the brick body itself to the permeable channel. The second pathway is through the permeable seams to the permeable channel. The third pathway is through the permeable channel and the horizontal pipe 6 to the drainage channel 4. The multiple pathways of rainwater flow increase the maximum permeability rate and prevent water collection and overflow when the rainfall is heavy.

[0055] Adjacent permeable brick bodies 5 are connected via the inserting plates 504 and the inserting holes, thereby improving the smoothness of the road surface.
